t A' further, object' is toprovrde a device which is capable of-'unit expansion thereby permitting the device to be employed upon floors of varying area. d

'Other objects and advantages Will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like Vnumerals are employedl to designate like parts throughout the same,

as the same would appear when laid upon .a concrete floor of a room, .a

Inlayinga Wooden floor over a concrete floor, it has been common to lay parallel spaced Wooden sleepers upon the concrete surface and due to the fact' that the concrete fioor Was seldom level, the result was that there Were high spots insonne places and It has therefore been-necessaryv to. place shims'or Wedges beneath the sleepers with the result that when the Wooden floor was laid u on the sleepers and nailed thereto, the act o. hammering often caused the shims to become misplace'd., 'resulting' in a i springy l floor, and Wheretlrel door was :of considerable area., the samek often had Waves therein.

In lorder to overcome 'thesefdiflicuities We have constructed a device. .for suppor'ting'a of Veach of said molds, being on the saine plane Withtlie resultl thatfvvhen, a plastic compositi on vis poured]V Withinc the l molds.y a smooth, even'vvith the ,top the molds and perfectly level 'set of-sleepers will b'e. formed.

Atthe same time, the' plastic'c'omposition will" Contact the. v@fortuiteflooring tluSjre- Y l f Sulte; in a one hundred-ner oel't" loteries throughout the v entire length ofthe sleeper.l

Inthe accompanying drawings vvherei'n-V 'forA the purpose o fj illustration is. shown a preferredembodiment of ourinvention, the

'numerals laand" 6 designate'the side Walls of a room andV the numeral7 the endwall thereof, while'tlie numeralS 'refers to a "concrete licor laid Within the room. The contourofthis f loor is best illustratedin Figure II, the unevenness ofvl the floorv hovvefv'er,v

being somewhat exaggerated so as to better illustrate our invention.

We employ a plurality of `jacket) Which i l' are provided With tripod legs l1. p Each O f these jacks has a threaded'member 12 having a lnurled hand Wheel 13 upon its upper extremity. A lock nut is shownat 1d While a straight edge lock 16'is threadedly sup-` Ink using ourf device,a plurality of these jacks are'positioned Within the roomas best I .v .illustrated in Figure I'. VThese jacksy serve several sections are employed, the ends are supported in notches 21 (see ,Figures III and'IV).

spreaders are employed, which preferably consistvofstrap iron members 29 ywhich lap I uponV eachother and arev fastened together Suitable perforation's arev provided in these members 2 9 so vthat the distance between the molds may be adjusted to suit conditions. Y
